non-essential amino acids‚ amino acid remodeling‚ and conversion of non-amino acid carbon skeletons into amino acids and other derivatives that contain nitrogen. However‚ the liver is the major site of nitrogen metabolism in the body. In times of dietary surplus‚ the potentially toxic nitrogen of amino acids is eliminated via transaminations‚ deamination‚ and urea formation; the carbon skeletons are generally conserved as carbohydrate‚ via gluconeogenesis‚ or as fatty acid via fatty acid synthesis pathways

Acid Rain and its Chemistry Acid rain is a type of pollution that is becoming a major threat to our planet and is need of attention. Acid rain has significantly increased ever since the industrial revolution‚ and now around the world‚ countries like Russia‚ China‚ and those in Europe are facing increasing levels of acidity in their rain. Not only is it becoming more acidic but it is also spreading by the pumping of sulfuric gasses deeper into the atmosphere from of the use of taller smokestacks

The Effects of Acid Rain Bio-105 Abstract The effects of acid rain is damaging no matter how you look at the picture. Acid rain effects open areas more than forests due to the trees blocking some of the rain from hitting the ground. Acid rain is monitored by using emissions monitors. This helps figure out how much acid is in rainwater. Acid rain is harmful to fish by killing off entire species. Acid rain is harmful to living creatures‚ but many do not realize how toxic it can be to
